The 29-year-old former Laguna Beach star took to Twitter on Sunday where she shared that the crash had dislocated her elbow, meaning she hasn't been able to carry her 2-month-old daughter, Saylor.
"Dislocated my elbow last Thursday and not being able to hold my baby is absolutely killing me," Cavallari tweeted.

The mother of three was rushed to the emergency room after her car was hit by another driver in Chicago on Thursday.
Reportedly, Cavallari's children were not with her in the car during the accident, and she was soon visited in the hospital by her husband, 32-year-old NFL star Jay Cutler, after being admitted.
The last few months have been hard for Cavallari. Shortly after giving birth to her baby daughter in November, Cavallari's brother, Michael, was reported missing. Days later he was found dead in Grand County, Utah.
